|
siliceous |
|
texture |
epidermis, trichome |
Containing deposits of silica, thus hardened and abrasive. |
|
silicle |

fruit |
Like a silique, but only slightly longer than broad to broader than long; esp. in Brassicaceae (Cruciferae), Capparaceae. |
|
silique |
|
nominative |
fruit |
Dry, septifragal, two-loculed and derived from a single, superior, compound ovary; much longer than broad; dehiscing along two sutures, one adaxial, one abaxial, leaving a single persistent septum (replum) after the two valves of the pericarp have fallen away; esp. in Brassicaceae (Cruciferae), Capparaceae. See also silicle. |
|
silky |
= sericeous |
pubescence |
|
Of or bearing long, fine, appressed, capillate trichomes and like silk to the touch. |
|
simple 1 |
|
architecture |
|
Externally unitary and comprising only one basic morphological unit; not compound in either sense of that term. |
|
simple 2 |
|
architecture |
trichome |
Unicellular and unbranched. |
|
simple-craspedodromous |
|
venation |
|
Having a midvein that branches to either side along the length of the lamina, the secondary veins and their branches all running toward and terminating at the margin. |
|
simple-lipped |
= haplocheilic |
architecture |
stomate |
Having subsidiary cells not derived from the primary stoma mother cell and thus not immediately related ontogenetically to the guard cells. |
|
single-… |
= mono…, one-…, uni… |
prefix |
|
Indicating presence of or constitution by one entity of the type denoted by the term's stem; as in single-celled, single-headed, single-seeded. See also entries for particular terms with this prefix whose meanings, at least in some applications, are more specific than usually indicated by such combination. |
|
single-leafleted |
= one-leafleted, unifoliolate |
architecture |
foliaceous structure |
Structurally compound but with only one leaflet, whose nature (as a leaflet, not a leaf) is revealed by an evident articulation with the petiole, this condition presumably derived by evolutionary reduction from a multifoliolate precursor. |
|
single-veined |
= hyphodromous, one-veined |
venation |
|
Having one median, primary vein and no other venation externally evident. |
|
sinistrorse |
= leftward |
orientation |
|
Directed to the left, relative to the direction of growth along an explicit or implicit axis of reference. See also dextrorse (rightward). |
|
sinuate |
|
margin |
|
Having regular, curved, smoothly connected, alternating concavities and convexities. See also repand. |
|
sinuous |
|
course |
|
Regularly wavy in one plane, curved alternately and more or less regularly to either side. |
|
sinus pl. sinus, sinuses |
|
FEATURE |
|
The space, indentation, or invagination (or, for some descriptive purposes, the outline thereof) between and delimiting any two consecutive or adjacent lobes or teeth of a structure. |
|
six-… |
= hexa… |
prefix |
|
Indicating presence of or constitution by six entities of the type denoted by the term's stem; as in six-angled, six-sepaled, six-styled. |
|
size |
|
CHARACTER |
|
Nature as to absolute or comparative extent in any one dimension or in area or volume. |
|
slashed |
= laciniate; < cut, incised, lacerate, torn |
plane shape |
|
Having relatively close, more or less straight lines of separation exending inward from the margin. See also cleft (dissected, divided, lobate, lobed, parted, partite, segmented). |
|
slipper-shaped |
= calceolate |
solid shape |
|
Relatively thin-walled with an essentially hollow interior that is open on one side at the broader end. |
|
small-beaked |
= rostellate |
apex |
|
Diminutively beaked (rostrate). |
|
small-bristly |
= setulose |
pubescence |
